Dopey the ducklegger
John “Dopey” Perry was an early law enforcement agent for the Department of Agriculture’s Bureau of Biological Survey— which after 1900 was given responsibility for enforcing the Lacey Act preventing illegal shipment or importation of wildlife and was the predecessor to the U.S. Fish and Wildlife Service.
The normally clean-cut Perry would go undercover as the hobo “Dopey” along the Chicago waterfront of the 1920’s to catch illegal wildlife smugglers (known at the time as “duckleggers”). (Photo/caption: National Conservation Training Center, USFWS)
